CORD-CLAMP.

SPECIFICATION forming pari: of Letters Patent No. 375,143, dated December 20, 1887.

(No model.)

.To (LZZ whom, it may concern,.-

Be it known that I, FREDERICK EGGE, a citizen of the United States, residing at Bridgeport, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Cord-Clamps; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to certain novel and useful improvements in cord-clamps, and has for its object to provide an exceedingly simple device of this character wherein the clamping shall be positive, while at the same time the cord may be loosened with great facility; and with these ends in View my invention consists in the details of construction and combination of elements, hereinafter fully set forth7 and then specifically designated by the claim.

In order that those skilled in the art to which my invention appertains may know how to make and use the san1e,'I will proceed to describe its construction and operation in detail, referring by letter to the accompanying drawings, forming a part of this specification, and in which-- Figure lis a perspective of my improvement, and Fig. 2, a central longitudinal section of the same.

Similar letters denote like parts in both figures.

Cord-clamps of this description are extensively used in fastening the mouths ofjute sacks, such as are common in the existing mail service, and in this connection they have been combined with holders for labels. I have therefore shown my improvement secured to a label case, and consequently especially adapted for use in said mail service.

A is the label-holder, and B the clamp-casing, riveted or otherwise secured to said holder.

that when in their normal position with relation to the cord they will be in a lower plane inverting the device and allowing them to fall by gravity. The free ends of the cord are now introduced beneath said tails against the noses of the dogs, which latter are readily elevated by the slight force required to push the cord through the clamp. By grasping the ends of the cord which project without the clamp the latter may be readily slid toward the loop of said cord, While the movement of the clamp in the reverse direction is impossible, because, since the plane ofthe tails`of the dogs is lower than that of the rear Wall of the casing, the impact of the cord against said wall causes the strain on the cord to force thetails of the dogs upward, thereby rnily depressing the noses of said dogs against the cord.

In order to release the cord, so that the latter may be manipulated in either direction, it is only necessary to depress the tails of the dogs, as will be readily comprehended from the drawings.

I claim- In a cord-clamp, the combination, with the casing open at the front end and closed at the rear, of two dogs pivoted in juxtaposition between the sides of the casing, said dogs having tails extended in proximity to and in a lower plane than the rear wall of said casing, whereby the impact of the cord against said wall will force said tails upwardpand thereby depress the noses of said dogs firmly against the cord, substantially as and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.

FREDERICK EGGE.
